Re: Leaking Heat Exchanger

Take the heat exchanger to a radiator repair shop to have it pressure tested. When they determine where it's leaking they'll probably be able to repair it on the spot.

Re: Leaking Heat Exchanger

Unless the body has gone porous with electrolysis a simple silver solder or braze can fix a fatigue crack or?? Too much heat can effect the tubes so careful.

Probably going to just go ahead and buy a new one. Going to take the part off for a looksie this weekend. But I hope there isn't an underlying problem which is creating too much pressure on the HE? The oil looks good (and pressure is steady at 40) , temp has been good too (around 180). I don't think it is a head gasket problem.

Re: Leaking Heat Exchanger

Can you provide any info on the HE? It would be nice to know the manufacturer, but at the very least the material. A picture would help.

While not technically a spot weld, a brazed repair might be possible, depending on the material. Some people have had success using JB weld type epoxy for pinholes and small cracks.

Leaking Heat Exchanger

Been noticing a small drip under the bottom of the bulkhead mounted heat exchanger. When I start the engine, it starts spraying a pretty decent amount. Is it possible to spot weld this part? I do not know how old it is.
Thanks.
